Heat transfer of power-law fluids with variable thermal conductivities on a horizontal rough surface

open access: yes工程科学学报, 2023
Power-law fluids have recently received increasing attention because of their applications in different industrial fields. In previous works, the energy and momentum equations for power-law fluids were considered the same as those for Newtonian fluids ...

Turbulent Bubble-Laden Channel Flow of Power-Law Fluids: A Direct Numerical Simulation Study

open access: yesFluids, 2021
The influence of non-Newtonian fluid behavior on the flow statistics of turbulent bubble-laden downflow in a vertical channel is investigated. A Direct Numerical Simulation (DNS) study is conducted for power-law fluids with power-law indexes of 0.7 ...

New Simple Analytical Surge/Swab Pressure Model for Power-Law and Modified Yield-Power-Law Fluid in Concentric/Eccentric Geometry

open access: yesApplied Sciences, 2023
The axial movement of pipe in and out of the well generates positive (surge) and negative (swab) pressures that will impact the well pressure. When the swab and surge effects cause well pressures outside the allowable operational limits, wellbore ...

Pipe Flow of Suspensions of Cellulose Nanocrystals

open access: yesFluids, 2023
The pipeline flow behavior of suspensions of cellulose nanocrystals (CNCs) was investigated over the CNC concentration range of 0.24 to 3.65 wt% in different diameter pipelines. The CNC suspensions were Newtonian below the CNC concentration of 1 wt%.

Numerical modeling of laminar and turbulent annular flows of power-law fluids in partially blocked geometries

open access: yesResults in Engineering, 2023
The presence of cuttings bed in deviated wellbores has an undesirable effect on wellbore hydraulics by reducing the open flow area. In addition, pipe eccentricity affects the annular frictional pressure gradient under such configurations.

Experiment-based Comparison of Prediction Methods for Pump Head Degradation with Viscous and Power-law Fluids [PDF]

open access: yesChemical and Biochemical Engineering Quarterly, 2022
Although several methods are known to calculate pump performance with highly viscous and non-Newtonian fluids, research has not yet determined all the key parameters of these predictions. It is unclear how these parameters depend on the pump geometry and

Reply to "Comment on Sochi's variational method for generalised Newtonian flow" by Pritchard and Corson [PDF]

open access: yes, 2015
In this article we challenge the claim that the previously proposed variational method to obtain flow solutions for generalized Newtonian fluids in circular tubes and plane slits is exact only for power law fluids.
